PILING.

Application filed October 23, 1326 Serial No. 1433770.

The present invention relates to woocl piling and preservation ot the same.

Heretofore, it has usually been customary in the treatment of piles to preserve then, to v for apparatus and treating liqnid. And the driving of extremelyiong piles also requires nnusual apparatus.

Among the objects of the present invention therefore, is to overcome these diiliculties and efi ect an economy in both the preserving and placing ot' piling, particularly piling of unusual length.

Other objects will readily appeanto those skilled in the art upon reference to the following description and drawing inwhich a preferred orm of enbodi'nent of the invention is described and illustrated and in which Fig. l is an enlarged vertical section of a portion of the pile of Fig. 2.

F 2 is a more or less diagraminatic View in' elevation of a pile einbodying the invention. I

As indicated in the drawings the pile is preferably formed of two portions of which the pointed or lower end portionA will be untreated with preservative, The upper end portion B will be of sufiicient length to ei:- tend down a short distance below the fixed This portion B will be treated with preservative. A

The two parts are Secured together by nieans of a metal sleeve C into which adjacentends of parte A and B will extend and which issecured to theseends by spikes D or other suitable means. i

This form ot pile is especially useful when i it is necessary to drive 'exceptionally long piles, as the lower portion may be sunk for a considerable portion of its length before attaching the upper portion.` This means that with apparatus capable of handling up to a certain length of pile, piles of approxinate inultiples of that length may be driven,

as the present -piles may be made in more than two sections with only the upper seotion of preserved piling.

'In those cases where it is necessary to sink verylong piles and to drive the lower part independently of the first, it is preferred to provide this part with a ring Eto ,keep the end froni splitting or spreading; This ring is left on and the sleeve G put over it.

Further, as it is usual to cut ofi' the upper end of piles to even them or for sone other reason, this part may be bored axially tera 'few teet so that the preservative may pene- V trate properly that part which becomes the 7 end after the part's'is sawed oil". The lower end oi" such a 'hole is indicated at F.

Having 'now described the invention and the preterred orn of embodnnent thereof it is to be understood that the said invention is not to he limited to the specific details herein described and shown but only by the scope of 'the clains which follow;

i clainx I l. A sectional wood pile coinprising a lower unpreserved section adapted to be completely below water level and an upper sec tion which has been treated with a preserva tive.

2. A sectional-wood pile comprising a lower untreated section, an npper preservative treated section seated thereon and a i metal sleeve extending longitudinally over the adjacent ends to prevent lateral displace-' ment. i
